5/16 in. Flare x 3/8 in. Male NPT Stainless Steel Adapter
5/16 in. Flare x 3/8 in. Male NPT Stainless Steel Adapter
Overview
The Midland 10261SS is a stainless steel SAE 45-degree flare adapter joining a 5/16 in. male flared tube end to a 3/8 in. male NPT pipe thread. Machined from corrosion-resistant stainless steel, it carries a 1000 psi pressure rating and suits copper, brass, aluminum, and steel hydraulic tubing where chemical resistance matters.

Frequently Asked Questions
Is the flare end SAE 45-degree?
Yes. The 5/16 in. flared end uses the SAE 45-degree seat standard for refrigeration and hydraulic tubing.
Does the NPT end need sealant?
Yes. Apply PTFE tape or pipe dope to the 3/8 in. male NPT threads; the flare seat seals metal-to-metal and needs none.
Why stainless instead of brass?
Stainless steel resists corrosion in marine, chemical, and high-purity systems where brass may degrade.
What tubing does it fit?
Copper, brass, aluminum, and steel hydraulic tubing prepared with a 45-degree flare.
